Definitions

• the present invention concerns a privacy screen filter for mounting on screens of computers, including particularly screens on portable computers such as laptops and/or tablet pes, on which a camera and/or a sensor is mounted in the computer screen, such as in the edge frame of the screen, and wherein the screen filter includes a filter element in the form of a film sheet with means to prevent other than the user to see the contents on the screen, such as a film sheet including micro -lamellae and one or more mounting means for releasable fastening of the screen filter along at least one edge of the screen.
• computers in particular portable computers or laptops, in many connections, and often they are used in public areas as well where it is possible for others to see the display on the screen if they are in the vicinity of the user of the portable computer.
• a privacy screen filter is a film or similar which is made with vertical micro-lamellae that prevent persons standing or sitting beside the laptop user from seeing the contents on the screen and reading/seeing potentially confidential data shown on the screen. The user himself has a clear screen image when the screen is viewed from a position largely perpendicular to the screen.
• these screen filters are mounted on the screen by adhesive pads, Velcro® bands, where one part of the Velcro band, e.g. the hook part, is mounted on the edges of the screen and the other part, e.g. the loop part, is mounted on the edge(s) of the screen filter.
• Velcro® bands where one part of the Velcro band, e.g. the hook part, is mounted on the edges of the screen and the other part, e.g. the loop part, is mounted on the edge(s) of the screen filter.
• one part of the Velcro band e.g. the hook part

• US 2007253065 discloses a privacy screen filter of the kind mentioned in the introduction. This screen filter is not suited for safeguarding against misuse of a camera and/or sensor mounted in the computer screen.
• the privacy filter is adapted for mounting on screens of computers, including particularly screens on portable computers such as laptops and/or tablet pes, wherein the screen filter includes a filter element in the form of a film sheet with means to prevent other than the user to see the contents on the screen, such as a film sheet including micro- lamellae and one or more mounting means for releasable fastening of the screen filter along at least one edge of the screen.
• the privacy screen filter according to the invention is peculiar in that the screen filter additionally includes one or more reinforcing plate- shaped elements mounted along the front side and/or the back side of the upper and lower edges of the film sheet or of the side edges of the film sheet, and preferably across the entire width and height, respectively, of the film sheet for reinforcing the film sheet, and that the reinforcing plate- shaped elements and the film sheet all along at least one edge of the film sheet include a through-going hole, and that a movable slide is mounted in connection with the hole aperture as the movable slide can close the aperture or allow the aperture to be free.
• the upper reinforcing plates and the film sheet include at least one through hole going through all two or three layers. This through- going hole is disposed in an area in which a camera and/or a sensor is mounted in the computer screen, such as in the edge frame of the screen.
• a movable slide is mounted at the hole aperture as the movable slide can close the aperture or allow the aperture to be free.
• the slide is arranged to slide back and forth or up and down in the aperture in the through-going hole.
• the slide is preferably loosely placed in the hole in the film sheet, having a thickness less than the thickness of the film sheet.
• the hole in the film sheet is therefore preferably larger than the holes in the front and rear upper reinforcing plates.
• the hole in the film sheet therefore also has a size and a shape allowing the slide to be slid up/down or sideways back/forth, thereby freeing a substantial part of the aperture in front of camera and/or sensors, or covering the aperture in front of camera and/or sensors.
• the back side of the foremost upper reinforcing plate can have a depression in the area around the hole, allowing the slide to lie in the depression and be pushed back/forth or up/down for covering and opening, respectively, the aperture in front of the camera/sensors of the computer.
• the slide preferably includes an control handle with a height exceeding the thickness of the foremost reinforcing plate so that the user can easily operate the slide and close or free the hole in front of the camera and/or sensors.
• the mounting means include one or more hook elements, where the hook elements engage the upper edge of the film sheet or the reinforcing plate- shaped elements.
• the hook elements are adapted to grip over the upper horizontal edge of the screen with a hook member and are thus adapted for releasable fastening of the screen filter at an upper edge of the computer screen.
• the screen filter By the engagement with the upper edge, the screen filter will hang stably on the upper edge of the computer screen.
• an upper horizontal edge in the present description is meant the upper edge which in normal use of the screen will be oriented approximately horizontally.
• the invention is achieved a privacy filter that is easy to mount on the screen without use of adhesive-based mounting means as described above.
• an aesthetically acceptable solution is achieved as there is no need for a permanent mounting of fastening means on the computer screen.
• the mounting means do not disfigure the computer thereby when the screen filter is not in used because the mounting means are mechanical and an integrated part of the screen filter, not leaving any trace on the computer when the screen filter is dismounted and not in use.
• the user When the user does not want to use the screen filter, it can simply be taken off by lifting the hook members off the edge of the computer screen, or possibly pulling the screen filter aside in order to release the grip of the hook parts around the upper edge of the computer screen. It is also possible for the user to hang the screen filter at the back side of the screen such that the screen filter is suspended along the screen housing, e.g. on a laptop, when the screen filter is not to be used. This will facilitate storage of the screen filter, at least temporarily, in close vicinity to the laptop on which the screen filter is normally applied. Of course it is also possible to take the screen filter off and put it in a storage case, e.g. in the form of a separate pocket in a case for the portable computer.
• the mounting means include magnets. These magnets are used for retaining the screen filter on an edge area, either at the bottom and top or at the side edges.
• Some computers have a metallic frame or frame part that enables fastening of a magnet to the frame or a part of the frame.
• a privacy filter that is easy to mount on the screen without use of adhesive-based mounting means as described above.
• magnetic mounting means an aesthetically acceptable solution is also achieved as there is no need for a permanent mounting of fastening means on the computer screen.
• the mounting means thereby do not disfigure the computer when the screen filter is not in use as the mounting means are magnets and an integrated part of the screen filter, not leaving any trace when the screen filter is dismounted and not in use.
• the magnets used can be moulded into the filter or embedded in other ways in the reinforcing plate-shaped elements, preferably in a way such that they do not project above the surface of the reinforcing plate- shaped elements. Magnets can be completely embedded or mounted in holes such that the surface of the magnets is flush with the surface of the reinforcing plate-shaped elements. Hereby any risk of the magnets scratching the frame of the computer is avoided.
• the magnets can be provided in one of the reinforcing plate-shaped elements or go through the reinforcing plate-shaped elements and the film sheet provided there between.
• the magnets can be provided in the reinforcing plate- shaped elements at an upper edge of the screen filter or at both the upper and lower edges of the screen filter.
• the screen filter includes a filter element in the form of a film sheet with means to prevent others than the user to see the contents on the screen.
• a film sheet e.g. of plastic, e.g. PET, polyethylene terephthalate.
• the film sheet has micro-lamellae that are angled such that the screen is completely visible if the user is situated largely at right angles in front of the screen, whereas the screen appears dark or black if the screen is viewed obliquely from the side.
• more layers may be provided, and that an outer layer can be made of other materials such as glass.
• two hook elements are used, provided at the upper edge of the screen filter and spaced uniformly from each of the vertical side edges of the screen filter.
• the hook elements will be provided at the upper end part of the reinforcing plate- shaped element.
• the width a between the gripping part of the hook member and the plane of the screen filter is adapted to the relevant screen or computer model on which the screen filter is to be fitted. Also, the height b of the hook member can vary according to screen or computer model.
• the hook member prefferably made with a certain resilient yieldability such that an elastic squeezing force against the screen housing is found after application.
• the hook can be made with an angling between the parts of the hook such that the spacing between the gripping parts of the hook member is the largest at the mouth in order to facilitate application on the screen housing.
• the hook element includes at least one mounting member in the form of a male part engaging a female part at the side edge of the film sheet, as the female part is designed as a cutout at the upper edge of the film sheet with a shape corresponding to the shape of the male part, and where the female part allows insertion of the male part in a direction perpendicular to the plane of the film sheet, at the same time preventing the male part from being removed from the female part in a direction in the plane of the film sheet when the one or to reinforcing plate- shaped elements are fitted along the front side and/or the back side of the upper edge of the film sheet.
• the risk of the hook element being released from the screen filter is hereby obviated.
• two reinforcing plate- shaped elements are applied which are mounted along the front side and the back side of the upper edge of the film sheet or the side edges of the film sheet such that the mounting member of the at least one hook element is clamped between the reinforcing plates.
• the at least one reinforcing plate- shaped element is mounted along the front side and/or the back side of the upper edge of the film sheet or the side edges of the film sheet by gluing.
• the hook elements are secured to the film part by engagement with the upper edge of the film sheet.
• the hook element includes at least one mounting part in the form of a male part engaging a female part in the film sheet.
• the hook elements may alternatively be fastened to a reinforcing plate.
• the male part is an integrated part of the hook member and parallel or at least substantially parallel with the gripping part of the hook.
• the male part preferably has a design in that the outer and thereby lowermost part of the male part are provided increased width in at least one, preferably both lateral directions relative to the uppermost and narrower part of the male part.
• the shape of the outermost wide part of the male part is not important and can be adapted to the production. It is thus possible that the outer part is edged, e.g. square, rhombic, rectangular or alternatively round or oval. If a single wide hook element is used, this will preferably include two or more mounting parts. These mounting parts are then preferably disposed with uniform spacing in order to ensure stability in the screen filter construction.
• the female part is designed as a cutout in the upper edge of the film sheet with a shape corresponding to the shape of the male part.
• the female part thereby allows insertion of the male part in a direction perpendicular to the plane of the film sheet while at the same time the male part can be taken out of the female part in a direction in the plane of the film sheet, e.g. if pulling downwards in the film sheet.
• the number and disposition of female parts are adapted to the number of male parts and relative to the total width of the screen filter and thereby also to the width of the relevant computer or screen model to which the filter is produced. This contributes to the screen filter hanging stable at the upper edge of the computer screen.
• the reinforcing plate-shaped elements of the screen filter mounted along the front side and back side of the upper edge of the film sheet preferably have the same width as the width of the film sheet. This will contribute to protect corners and upper edge of the screen filter. When using two reinforcing plates, this will ensure clamping of the film sheet and retention of the male parts of the hook elements in the female parts in the film sheet between the reinforcing plates.
• the reinforcing plates can be fastened to the film sheet and possibly to each other in commonly known ways, e.g. by gluing, click-lock elements, rivets, screws, etc.
• Hook members and reinforcing plates are preferably made of plastic, e.g. ABS plastic (acrylonitrile butadiene styrene copolymer) or metal, e.g. aluminium, iron or steel.
• the hook members are preferably of metal as this reduces the risk of breakage of the hook members.
• the inner side of the hook part which is adapted to be in contact with the housing of the computer screen, includes a coating.
• the coating serves to reduce or eliminate the risk of the gripping part of the hook scratching the screen housing.
• the coating can be in the form of a layer, stripes or knobs.
• the coating material is typically a plastic or rubber selected such that the coating is of a softer material than the computer screen housing in order to avoid scratches on screen housing.
• flannelette is used for the coating.
• the back side of the upper rear reinforcing plate can be designed with a corresponding coating in order to reduce the risk of scratches appearing at the edges of the computer screen when using the screen filter.
• the screen filter preferably also includes at least one and preferably two lower reinforcing plate- shaped elements which are mounted along the front side and back side of the lower edge of the film sheet, and preferably approximately over the entire width of the film sheet.
• the stability of the screen filter is increased hereby.
• the lowermost reinforcing edge provides weight at the bottom of the screen filter, contributing to the screen filter lying correctly on the computer screen and such that it cannot or only to a limited degree can flutter, e.g. associated with a draft or wind.
• the two lower reinforcing plates are similarly mounted as described above in connection with the upper reinforcing plates.
• the lower reinforcing plates can be connected along the lower edge of the screen filter for forming a U-profile.
• This U-profile can be mounted in the same way as described above, or possibly the U-profile is squeezed around the lowermost edge of the film sheet for simple and easy fastening.
• the back side of the lower rearmost reinforcing plate can be designed with a corresponding scratch-reducing coating as described above.
• Adhesive pads may be provided for retaining the lowermost part of the screen filter against the edges of the computer screen. The risk of the screen filter being inadvertently swung out from the edge of the computer screen is hereby reduced.
• These adhesive pads can be glue pads or Velcroband®.
• the screen filter according to the invention takes up sufficiently little of the total thickness in order that the user can let the screen filter be mounted on the computer screen of the portable computer and fold it around the screen filter without harming the computer or screen filter. However, it is preferred to dismount the screen filter before folding.
• Some computer models including particularly portable computers, have control buttons or rubber knobs, projections or locking mechanisms at one or more edge areas around the screen, e.g. for operating or closing the portable computer.
• the upper and/or lower reinforcing plates and/or the film sheet include(s) cutouts at the relevant areas of the screen filter, corresponding to the areas where such control buttons, locking mechanisms and/or rubber knobs are located on the edge areas of the computer screen.
